Cavernous hemangioma, also called cavernous angioma, venous malformation, or cavernoma, [1] [2] is a type of venous malformation due to endothelial dysmorphogenesis from a lesion which is present at birth. A cavernoma in the brain is called a cerebral cavernous malformation or CCM.
A millimeter-sized sea animal could hold clues to the evolution of the human nervous system. While placozoans are simple animals only as big as a grain of sand, the blobs have unique cells that ...
Marine sediment, or ocean sediment, or seafloor sediment, are deposits of insoluble particles that have accumulated on the seafloor.These particles either have their origins in soil and rocks and have been transported from the land to the sea, mainly by rivers but also by dust carried by wind and by the flow of glaciers into the sea, or they are biogenic deposits from marine organisms or from ...
Base rock can also be made from artificial rock called aragocrete, which is a hand made concrete from combining crushed aragonite, sand, and Portland cement. After allowing the cement to dry, the pieces are sometimes acid washed to counteract the high pH of the materials, and then allowed to soak in clean water for one or more months.
The gnome sea pen was named after the gnome, which researchers described as an “elemental spirit presiding over the ground.” The name refers to the way the sea pen appears to stand on a rock.
Sargassum is a genus of brown macroalgae in the order Fucales of the Phaeophyceae class. [1] Numerous species are distributed throughout the temperate and tropical oceans of the world, where they generally inhabit shallow water and coral reefs, and the genus is widely known for its planktonic (free-floating) species.
Unlike the worms living in the sand in the dunes of Arrakis, the fictional planet at the center of the “Dune” universe, this worm is incredibly small, but it does bear a remarkable resemblance ...
As the sand concentration of a flow increases, grain-to-grain collisions within the turbid suspension create dispersive pressures that become important in hindering further settling of grains. As a consequence, a slightly different set of sedimentary structures develops in turbidites deposited by high-density turbidity currents.
